About Wieser Septic & Excavating


 Len Wieser Plumbing was started in 1963 by Len Wieser, Sr. He did backhoe work including septic systems, city water and sewer lines, digging graves and was a master plumber. In 2006, Len retired and his son Len Wieser, Jr “Jake” took over the business and renamed the company Wieser Septic & Excavating.


  Jake is a licensed sewer installer, designer, and inspector and like his dad, installs septic systems, city water and sewer lines and digs graves. Jake has also expanded into all different kinds of excavation work from site clearing, demolition, driveways, digging basements and more. He is also a licensed general contractor in MN & WI and has built houses and commercial projects since 1989.


 Jake’s wife, Holly, works as the Chief Administrative Officer, along with many other hats and is also a licensed sewer installer. While you may not find her out on the jobsite very often, she is very involved with every job from inception to completion.


 In 2020, Jake & Holly’s oldest son, Wyatt joined the family business full time and is an exceptional equipment operator. In 2022, Jake & Holly’s daughter Madeline joined the team as Director of First Impressions and Easton, their youngest son, is quickly becoming a great operator and laborer.
